Storm is a distributed real-time computation system that processes streaming data and works with any programming language.

A MapR cluster that runs Storm includes:

  • A master node that runs Nimbus (the master node daemon)
  • Worker nodes that run Supervisors (worker node daemons)

Before you install Storm, plan which node will run Nimbus (the Storm master daemon) and the Storm UI, and which nodes will run the Supervisors (the Storm worker daemons).
